Word wrapping allows ElideLabel to resize first inside flexible sized
areas such as the contents widget of a scrollarea. This allows the contents
widget to properly resize itself to avoid horizontal scrolling.
Word-wrapping also enables the widget to resize vertically. To avoid that
ElideLabel is set to a fixed height based on font metrics. An overloaded
method `setFixedHeight` has been added to disable it when desired.
EglSyncGroup: Replace estimated path label with a ElideLabel because
the displayed message was expanding the scrollarea.
